thnx for rply bt if i purchase 48*24*24" = 120 us gallon tank, so is it sufficient for my 11 discus and can i keep left 3 discus as it is in current 28 gallon tank to grow them as per their natural average size instead of keeping all of them in such tiny place.

I've grown out discus in a 75 gal (over seven inches.) The key is good water, not extra large tanks; of course, with more fish (I had 5 in each tank), you'll need a bigger tank. The issue is mostly water quality - keeping BOTH nitrates and phosphates as close to zero as possible. In reality, without 100% water changes, aiming for under 1 ppm is more realistic. Of course, as I will post today, keeping phosphates under 0.5 ppm and nitrates under 1 ppm with only very small water changes is easy - a algae scrubber.
But using a very small, in tank commercial or kit algae scrubber is rather advanced stuff that very few people could ever handle - this requires cleaning the in tank scrubber at least once a week and running/operating an air pump and a cheap light timer: I am talking super advanced technology here that even scientist with backgrounds in chemistry and aquatics rarely attempt ... . OK, maybe a few really expert aquarist in the world might, maybe can handle this level of advanced work but that will be a secret that we won't let get around ...LOL.
Sorry, Mommy1 but I really need to wax ridiculous on this issue today.Knowledge is fun(damental)
A 75 gal with eight Discus, fake plants, and a lot of wood also with sand substrate. Clean up crew is down to just two Sterba's Corys. Filters: continuous new water flow; canister w/UV, in-tank algae scrubber!! Finally, junked the nitrate removal unit from hell.

I remember the experiment the famed discus keeper did with water changes vs tank size and discus growth, (I remember the experiment but not the famed discus keepers name, doesn't matter). My point is, he is a famed discus keeper, not a noob who appears to know little to nothing about fish keeping in general, never mind about discus specifically. Yes, the key in the experiment was all about clean water, however there comes a time when space is also required. I'm glad your little experiment worked out so well, however, there is a huge difference in 5 discus in a 75 gallon and 15 discus in a 28 gallon and to even hint to a beginner that keeping 15 or 11, the number changed, potentially large fish in a 28 gallon is doable for any length of time if he does enough water changes and tries that insipid algae scrubber is just irresponsible.
I agree with the advice of two or three large water changes daily, selling some of the fish, and getting a much bigger tank as soon as possible. Because the water change experiment by the famed discus keeper was proven to be effective, if you keep up with several large water changes daily, the fish will grow, and very soon 11-15 discus will need much more room to thrive.When I go fishing I just throw sharp rocks in the water and wait for the dead fish to float to the top...

Everything happens for a reason. Sometimes that reason is you are stupid and make bad decisions.
I think my fish is adjusting well to the four gallon, He's laying on his side attempting to go to sleep on the bottom of the gravel.
Imitation is the sincerest form of flattery.
Dear naps, sorry I hated you so much when I was a child... Love me

There is a waste product from the fish that is protein based. A result of spent or synthesized protein. It is a growth inhibiter and causes stunting. This is one of the factors that causes stunting. This factor may be over come by mass water change.
There is a second response that is driven by a chemical trigger within the brain of the fish. This trigger is enacted by the result of a physical dimension which is uncomfortable to the fish. This physical discomfort caused by lack of space causes the release of this growth inhibitor. This factor requires the larger space.
The protein factor happens fairly quick. If you don't do the water changes this happens right away.
The brain factor takes time as it only starts to happen when the fish are getting tight in the space, they have to grow towards that first so you get more time.
I believe this was the result of the Discus keepers findings.

The famed discus keeper you are referring to is the pioneer, Jack Whattley (spelling), I think.Mucky
Unusually I have nothing more to add...
